“…Phylogenetic relationships in Zygoptera have previously been considered chaotic, and a fully resolved phylogeny of Zygoptera does not yet exist. Past studies have only resolved parts of the Zygoptera family tree (Dumont et al, 2005;Sa ´nchez-Herrera et al, 2020;Vega-Sa ´nchez et al, 2019). Many of the traditionally recognized families, such as Amphipterygidae and Megapodagrionidae, as well as genera such as Agriocnemis and Pseudagrion have been shown to be polyphyletic (Dijkstra et al, 2014), which clearly hampers the compilation of a reliable taxon sampling to target deep phylogenetic relationships within Zygoptera.…”

Dragonflies and damselflies are among the earliest flying insects with extant representatives. However, unraveling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic relationships, particularly in damselflies. Here we present a transcriptome-based phylogenetic reconstruction of Odonata, analyzing 2,980 protein-coding genes in 105 species representing nearly all the order's families. All damselfly and most dragonfly families are recovered as monophyletic. Our data suggest a sister relationship between dragonfly families of Gomphidae and Petaluridae. According to our divergence time estimates, both crown-Zygoptera and -Anisoptera arose during the late Triassic. Egg-laying with a reduced ovipositor apparently evolved in dragonflies during the late Jurassic/early Cretaceous. Lastly, we also test the impact of fossil choice and placement, particularly, of the extinct fossil species, yTriassolestodes asiaticus, and yProterogomphus renateae on divergence time estimates. We find placement of yProterogomphus renateae to be much more impactful than yTriassolestodes asiaticus.

“…The commonly used empirical thresholds for the threshold-based species delimitation of the COI gene include 1%, 2%, 2.2%, and 3% [ 7 , 10 , 24 , 27 , 28 , 29 ]. Furthermore, a high genetic distance of the COI gene is usually used to predict cryptic or new species [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. It is widely accepted that the genetic variation in the COI gene has had a great effect on the final results of species delimitation studies.…”

The genetic variation in the COI gene has had a great effect on the final results of species delimitation studies. However, little research has comprehensively investigated the genetic divergence in COI among Insecta. The fast-growing COI data in BOLD provide an opportunity for the comprehensive appraisal of the genetic variation in COI among Insecta. We calculated the K2P distance of 64,414 insect species downloaded from BOLD. The match ratios of the clustering analysis, based on different thresholds, were also compared among 4288 genera (35,068 species). The results indicate that approximately one-quarter of the species of Insecta showed high intraspecific genetic variation (>3%), and a conservative estimate of this proportion ranges from 12.05% to 22.58%. The application of empirical thresholds (e.g., 2% and 3%) in the clustering analysis may result in the overestimation of the species diversity. If the minimum interspecific genetic distance of the congeneric species is greater than or equal to 2%, it is possible to avoid overestimating the species diversity on the basis of the empirical thresholds. In comparison to the fixed thresholds, the “threshOpt” and “localMinima” algorithms are recommended for the provision of a reference threshold for threshold-based species-delimitation studies.

“…Hetaerina americana had been recognized as a widely distributed species until very recently, when a cryptic species complex was suggested for the American rubyspot, possibly integrated by three species 16 . Moreover, this “species” has been extensively used as an ecological model for behavioral studies and diverse mating tactics have been described.…”

Incomplete premating barriers in closely related species may result in reproductive interference. This process has different fitness consequences and can lead to three scenarios: niche segregation, sexual exclusion, or reproductive character displacement. In morphologically cryptic species, isolation barriers can be difficult to recognize. Here, we analyzed the morphological, behavioral, and genetic differences between two sympatric cryptic species of the genus Hetaerina to determine the characters that contribute the most to reproductive isolation and the effect of the high rates of behavior interference between the species. We found complete genetic isolation and significant differences in the morphometry of caudal appendages and wing shape, as well as body size variation between species. In contrast, we did not find clear differences in the coloration of the wing spot and observed high rates of interspecific aggression. Our results suggest that divergence in the shape of the caudal appendages is the principal pre-mating barrier that prevents interspecific mating. Moreover, a scenario of character displacement on body size was found. Nevertheless, size could play an important role in both inter- and intrasexual interactions and, therefore, we cannot differentiate if it has resulted from reproductive or aggressive interference.
